Minor MLB Transactions: 4/20/17

Veteran right-hander Jim Miller has retired from playing (Twitter link). The 34-year-old, who last saw the Majors in 2015, was a reliable member of the Athletics’ bullpen back in 2012 when he tossed 48 2/3 innings with a 2.59 ERA, 8.1 K/9 and 5.0 BB/9. Miller never saw much action outside of that stint, though, as he logged a total of 67 1/3 innings in the Majors with a 3.48 ERA. Miller, a veteran 13 minor league seasons, was with the Twins in Spring Training but has now decided to pursue opportunities in player development.

The Athletics announced Thursday that they’ve selected the contract of right-hander Cesar Valdez, who started tonight’s game for them. In order to clear a 40-man roster spot, they moved Marcus Semien, who is recovering from surgery to repair a fractured wrist, to the 60-day disabled list. Catcher Bruce Maxwell was optioned out to Triple-A to clear room on the active roster for Valdez. The 32-year-old Valdez’s appearance tonight somewhat remarkably represents his first Major League action since the 2010 campaign, when he made nine appearances (two starts) for the Diamondbacks. Valdez has just 20 Major League innings under his belt but has a 4.40 ERA with 7.5 K/9 and 2.6 BB/9 over the life of nearly 400 Triple-A innings in his career.
